Here's a true nordic viking, bathing in ice-cold water. He like's chopping up holes in the ice and take a nice bath in them. He also like to have a sip of vodka.

Focus: Would you do this? If he fails and gets under the ice, how big is the risk of a fatal accident?

Yep, pretty standard nordic behaviour. We get out too much.

Let's just say that when I saw him dive into the ice cold water, my first reaction was "no, dear god, why?!"

It's extremely healthy to do (and be able to) take a quick bath in icy water. At least according to some sources.

It's too cold for me though.

I'm surprised the thin ice didn't break under the weight of his ginormous testicles.
